Abstract

New macrocyclic polyether compounds containing a 2,5‐bis(2‐hydroxyphenyl)‐1,3,4‐oxadiazole moiety are quickly prepared by a nucleophilic substitution reaction involving ethylene glycol ditosylate or polyethylene glycol ditosylate and a biphenol, the 2,5‐bis(2‐hydroxyphenyl)‐1,3,4‐oxadiazole, with solid anhydrous potassium carbonate as a base under microwave irradiation (monomode and multimode). The structures of new macrocyclic polyether compounds were confirmed by ^1^H, ^13^C NMR, mass spectrometry, and elemental analysis. J. Heterocyclic Chem., (2010).

## Abstract magnified image The syntheses of new macrocyclic compounds are described. The 2,5‐bis(hydroxyphenyl)‐1,3,4‐thiadiazole reacts with allyl bromide to give the corresponding allyloxy derivative. The allyl is used to functionalize the ortho position by means of a Claisen rearrangement unde
